The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems VIII: patchy forsterite and enstatite clouds in the atmosphere of VHS 1256 b, retrieval lessons learned and outlook to the future
Niall Whiteford, Jacqueline K. Faherty, Ben Burningham +123
JWST defines a new era for the data-driven approach of retrieval modelling, which has become a cornerstone tool for the statistical inference of exoplanetary and brown dwarf proper…
JWST spectral retrieval of cold directly imaged planet WD0806 b and the first measurement of altitude-dependent K in exoplanet atmospheres
Ben W. P. Lew, Thomas Roellig, Natasha E. Batalha +10
WD0806 b is a rare exoplanet companion orbiting a white dwarf, currently with a projected orbital distance of 2500 au. The Spitzer mid-IR photometry suggests that the temperature i…
First Demonstration of Kernel Phase Interferometry on JWST/MIRI: Prospects for Future Planet Searches Around Post Main Sequence Stars
Chelsea Adelman, Steph Sallum, Matthew De Furio +1
Kernel phase interferometry (KPI) is a post-processing technique that treats a conventional telescope as an interferometer by accurately modeling a telescope pupil as an array of v…
The Hubble Ultracool Multiplicity (HUM) Survey. I. Characterizing Sensitivity to Companions at Sub-Diffraction Limit Separations with HST WFC3/IR
Kunal Mehta, Matthew De Furio, Daniella Bardalez Gagliuffi +6
We characterize the sensitivity of a double point-spread function (PSF) fitting algorithm -- employing empirical, position-dependent PSF models -- for detecting companions using th…
Wavefront Error Recovery and Companion Identification with the James Webb Space Telescope
Matthew De Furio, Marie Ygouf, Alexandra Greenbaum +8
The James Webb Space Telescope is orders of magnitude more sensitive than any other facility across the near to mid-infrared wavelengths. Many approved programs take advantage of i…
The Small Separation A-Star Companion Population: Tentative Signatures of Enhanced Multiplicity with Primary Mass
Matthew De Furio, Tyler Gardner, John D. Monnier +6
We present updated results from our near-infrared long-baseline interferometry (LBI) survey to constrain the multiplicity properties of intermediate-mass A-type stars within 80 pc.…
